T all whom t may Gomera i V Y -Be 1t known that we', IsAaoFLEMING and HUGH S. llrrmboth'citizens of the UnitedV 1-States, residing at Los Angeles, in' 'theV county of Los Angeles and State ofCali.-l forma, have jointly invented new `and use,-

. ful Improvements in'fMachines for Cutting V1Vents i in Automobile-Hoods, of which the following is a specification.

. The present invention relates to a machine for Acutting vvents or `louvers *inl sheetv metal articles such as the hoods of automobiles,

such vents being commonly provided to faf l cilitate a Afree circulation of air around the engine and to prevent the heated air from passing back into the body'of the vehicle,

the object ofthe invention being to lprovide 1 a'device of-,this character which embodies v novel featuresgof construction whereby theV vents or louvers can be .quickly and inexpensively formed in the sheet metal Vwith a h minimum amount of laborand with a very small outlay of capital for machinery.

Further objects of the-invention are to' provide va machine of'this character which heavy strains to which it is subjected in use without danger of* being broken'` or twisted out ofi shape, and in which dilferent cutreference is to be had to the following de- *Y A scription and accompanying drawing 'in tingy and shaping members areinterchangel able so that proper adjustmentca-nbe madeY for forming different sizes andshapesf of vents. v

-With these and other obje-cts view, as

will more fully appear' as the description proceeds, the invention consists in certain combinations, arrangementsl and associations of parts, l,the novelV features thereofv being pointed out in the appended claimsj For a full understanding of the invention which Figure l; is a been partially operated upon being lshown in .operative position'fwithin the' machine ,and the handle ,being broken away;

It will be noted that the edge of the` swinging arm-'4 to` which the cutting' andshaping element 5 -issecured is arranged in a line which passes longitudinally :through the offset-portion 4 ofthefswinging end of the armat substantially the middle point thereof, andwhich also passes through the bifurcated pivot end .of the rswinging arm at substantially themiddle .point there- "#of. The heavy strains which would be due Y, jeven: a distribution of f is possible.

to anofi'set arrangement of the cutting and 'shaping element 5 are thus avoided and the said cutting yand shaping elementV is positionedrin such a manner as to' provide for as The vfixed cutter y.andi-shaping element which'are provided for cooperation with the Y vmovablecutting and Ashaping element 5 are' f Vmounted upon the bed plate 17 and the sheet :metal arti-cle A fwhich is to be operated upon is intermittently moved acrosstlie top of the said members' as the machine Lis operated.

The cutting and shaping element 5is detachnishedin different' lengths and` thicknesses' An, VVequipment which. ywould be useful in .manysmall lshops would include threev di'erentlengths of the cutting .and

shaping element 5. Fig. Y6 shows cutting and shapng'felements 5a and 5? which are of different;lengths and can be used interchangeably Vwith the, cutting and shaping element 5,., thereby `enabling adjustment., to

. Abe maidevfor cutting. three diiferentllengths of vents. -Of' course many other shapes and A sizes of cutting and shaping elements-1 may be used.interchangeably,`if desired.V

The fixed cutting anddie elements are Vadjustable to 'cperatewith Athe particular cutting and shaping elementl which is .mounted upon thesw'ingingjarm 4l. In the p `present-instance the fixed member' which is arranged upon'the bed plate 1 includes a pair of shaping-,blocks 17 having va'knife bar V18 interposed between Vthe same, and knife t bars l123 ap'pliedL-to the vouter sides thereof;`

VThe blocks 17 are providedin edge portions thereoffwith :dier openings or" shaping recesses 19a-,19?y and 19 which are of different -`leng'gths and-properly lshaped for cooperation withgthe different .cutting and shaping elements 5, 5,a 'and 5b. Theinembers 17 and 18 can bel-positioned upon. the bed plate 1 to the-heavy strains asV p A y l c j or louvers vmay beforined', as indicated'by 'Fim 5. .y

i holdy anyone ofthe die openings 19, 19b

or 19c andthe corresponding knife bar 18 in proper position lfor cooperation with the y cutting and shaping elementontlieswinging arm 4 to cut a slit B in the sheet metal blank A and simultaneously press out and shape an edge portion of the'slit to form a louver C each time the operating lever 13 is' swung downwardly. By reference toFig. 4 it will be observed thatv the cutting and shaping element 5 has a thickness corresponding tothe width -of the-i louver C to be formed, land that'one edge 'thereofis sharp forcoperation with the knife bar 18. to slit thesheet metal, while the other edge thereofl is rounded and'shaped to forma punch which Iwill *coperate withv thefdieA opening or recess fof the 'block-17 to shape the sheety metal on one` side ofthe slit-'and form a louver C. I The'she'et metal blank y is advanced step by step between the'operations `of the machine,and a lseries of vents buitable gage or guide strips 20 maybe providedfor directing the sheet metal blank A as it is moved through the machine7 thereby-enabling the several ventsorlouvers C- to be formed iii the proper relation to. each other. These guide vstrips 20 extend transversely. across the bedplate land aifesupported by u-prights 21 at the kextremities thereof, -said uprights l being formed' withg;

slotted arms 22r which project klaterally from the lower ends 4thereof andare adjustably screws 23. This arrangement enable'sthe e 10o connected to theblock 2 by means Vof the y l `guide strips to be moved toward and away e n fromeach other and properly`v adjusted' toy direct the particular sheet 'metal'kblank A being operated upon through the machine inV the proper-manner. Y f

Arranged'under the swingingvarmft and at one side of the cutting and shaping ele-- `Inefnt 5 is a pressurefootVv and sto'p24 which isadjustalbly supported from the 'swinging arm; by the screws 25. By suitably manipufy i lating these screws the pressure foot can be moved towardA and away'r from the Swinging arm and vproperlyadjusted. ln. the operationof ythe machine this .pressure foot 24' engages the portion ,of the sheet metal blank A adjacent to the'slitand' presses the same vagainst the die vblr c'k,tliereby smoothing out and removing any bulges y or wrinkles` Vwhich might have a tendency to form in the Y sheet metalrblan'k at the time theV iin or vlouverC is pressed'therefrom. kThe'smoothnessv ofv the body is thus preserved"'and n clear-cutstamping action' obtained in forin-` ing the vents.

TheV fixed die biock which; inv the present 17y 'and three knife `bars 18,`may be conveniently positioned in .the proper manner-' instance, is a composite ofthe two blocks` by fitting it in a recess 26 in the upper snr-y face of the bed plate 1. vThe several members 17 and 18 may be held together .by the l tie bolts 27so as to form a single membery which can be handled as a unit. vrA'lhe' recess 26 has a width greaterthan that of the' coinlposite die member, and a filler strip 28 is-` fitted in one side ofthe recess to` hold the f Suitable composite die block in position. fastening members such as the: screws 29 may be utilizedto holdthe filler strip28. in position. y.T he composite dierblocl'may bey bodily lifted out of position and reversedu to bring either one-of the outerlmifebars 1 18 and v,die openings 19a, or 19c into opera-` tive position. In order to bring the inter- 'mediate knife; bar 18 and dieY opening 19b into operative'position the composite die block is shifted laterally in the-recess 26 by removing the filler strip 28 and replacing it in the opposite side of the recessafterthe necessary adjustment of-V the composite diey block hasv taken place. It 'will bewunder- 1 stood, of course, that when one of thelmife r bars and die blocks is placedinoperative be applied to the swinging arm 1l.

louvers which are ordinariry founddesirable when working upon Y automobilehoods.

Each time the lever is operated the'sheet' metal blank will have a slitcut -therein and the portion of the metal at one side of the slit pressed downwardly and shaped to form a louver. This lever'may be operated by hand power, foot power, or by machine,

as may be found most desirable.

Vlhile we have illustrated and described one particular embodiment offour invention, it will be understood that numerous changes and modifications can be made therein without departing from the scope and intent of the invention as defined by the appended claims.
